What Is Scarring Alopecia?
Scarring alopecia, known clinically as cicatricial alopecia, is a category of conditions in which inflammation or direct damage destroys the hair follicle and replaces it with fibrous scar tissue. Once this process is established in a given area, the follicle cannot recover, and hair will not regrow. This irreversibility is what distinguishes scarring alopecia clearly from the majority of hair loss conditions encountered in clinical practice.
Scarring alopecia is not a single diagnosis but a grouping that encompasses several distinct conditions with different underlying mechanisms, affected populations, and management requirements. What they share is the same end result: permanent follicle destruction. Because progression may be slow and subtle in some types, individuals sometimes live with active disease for months or years before seeking assessment. By that point the extent of irreversible loss may already be considerable. Early recognition and prompt referral to a dermatologist represent the most important factors in limiting long-term damage.
The psychological impact of a permanent hair loss diagnosis is significant and should not be underestimated. Unlike many other forms of hair loss, there is no expectation of spontaneous recovery. Managing the emotional dimension of this experience is part of good clinical care, and it is something we take seriously in all consultations at Regener8 Aesthetics.
Scarring alopecia is characterised by irreversible destruction of the hair follicle and replacement by scar tissue. It is categorised as primary, where the follicle is the direct target of the disease process, or secondary, where follicle destruction results from an external event or broader tissue injury. The primary goal of management is to halt progression, not to restore lost hair. Formal diagnosis requires dermatological assessment and, in most cases, scalp biopsy.
Symptoms and Warning Signs
The symptoms of scarring alopecia vary by subtype, but several features are common across the group and should prompt clinical assessment without delay:
- Patches of hair loss in which the affected scalp appears smooth, pale, or shiny, with no visible follicular openings
- Redness, scaling, or crusting at the margins of the hair loss, particularly around individual follicles (perifollicular erythema)
- Itching, burning, or soreness on the scalp, especially at the active edge of the affected area
- A slowly receding frontal hairline, often accompanied by eyebrow and eyelash thinning, in frontal fibrosing alopecia
- Central thinning that spreads outward from the crown, characteristic of central centrifugal cicatricial alopecia
- Irregular, poorly defined patches that increase in size over months or years
- Pus-filled follicular lesions or boggy, inflamed areas in folliculitis decalvans
- Areas of thickened, discoloured, or atrophic skin in discoid lupus erythematosus affecting the scalp
A key distinguishing clinical feature of most scarring alopecias is the absence of follicular ostia within the affected area. In non-scarring conditions, these pore openings remain visible. Their absence on examination is an important indicator that warrants further investigation.
Types and Causes
Scarring alopecia is divided into primary and secondary forms, depending on whether the follicle is the direct target of the disease or collateral damage from a broader process.
Primary Scarring Alopecias
Lichen planopilaris (LPP) is an autoimmune condition in which lymphocytes target the follicle, leading to inflammation and eventual fibrosis. It presents as small patches of hair loss with perifollicular scaling and erythema, with symptoms including itching and burning at active sites. It can affect any area of the scalp and is more commonly seen in women.
Frontal fibrosing alopecia (FFA) is now considered a variant of LPP that specifically targets the frontal hairline, causing a band-like recession that moves progressively backwards. It is most commonly seen in postmenopausal women, though its reported incidence in premenopausal women has been increasing. Eyebrow and eyelash loss frequently accompanies scalp changes. The underlying cause involves immune dysregulation, though the precise trigger is not fully understood.
Discoid lupus erythematosus (DLE) is a form of cutaneous lupus that can affect the scalp, producing inflamed, scaly plaques that are often hyperpigmented or hypopigmented. When follicle destruction occurs, the resulting hair loss is permanent. Systemic lupus should always be considered and excluded through appropriate investigation.
Central centrifugal cicatricial alopecia (CCCA) begins at the vertex of the scalp and spreads centrifugally outward. It is most commonly seen in women of African descent and represents one of the most prevalent forms of scarring alopecia in this population. Genetic factors are now recognised as significant contributors to CCCA. This condition warrants culturally sensitive discussion: while some historical literature emphasised certain hairstyling practices as the primary cause, current evidence points to a complex interplay of genetic susceptibility, inflammatory processes, and environmental factors. Any consultation involving CCCA at Regener8 Aesthetics is approached with this nuance and with respect for each person's background and experience.
Folliculitis decalvans is characterised by recurrent painful follicular pustules and crusting, leading to expanding scarred patches surrounded by tufted hairs. It is more common in men and requires ongoing dermatological management, typically with prolonged antibiotic courses and in some cases isotretinoin.
Secondary Scarring Alopecias
Secondary scarring alopecia results from damage to the scalp from external causes. Burns, radiation therapy, severe fungal or bacterial infections, and chronic traction injury severe enough to cause permanent follicle damage can all lead to irreversible hair loss through the same mechanism of follicle replacement by scar tissue.
Scarring alopecia is not reversible once established. The primary clinical objective is to identify the condition as early as possible, confirm the diagnosis through appropriate investigations, and initiate disease-specific management through a dermatologist or GP to halt further follicle loss. Hair that has already been lost in scarred areas will not return.
Who Is Affected?
Scarring alopecias as a group are less common than non-scarring types such as androgenetic alopecia or telogen effluvium, but they are not rare. The populations most affected vary substantially by subtype.
Lichen planopilaris most commonly affects women, with peak incidence in the fourth and fifth decades of life, though it can present at any age. Frontal fibrosing alopecia has seen a marked increase in reported incidence over recent decades, predominantly in postmenopausal women, though the reasons for this are not fully understood and remain an active area of research.
Central centrifugal cicatricial alopecia disproportionately affects women of African descent. Estimates suggest it may be present in a substantial proportion of this population, many of whom have not received a formal diagnosis. Awareness and sensitive clinical assessment are important in ensuring this group receives appropriate care and timely referral.
Folliculitis decalvans affects men more frequently than women and can begin in young adulthood. Discoid lupus erythematosus affecting the scalp occurs across both sexes and all ethnic groups and carries implications for systemic disease that always warrant medical assessment.
Secondary scarring alopecia can affect anyone who has experienced significant scalp injury. Individuals who have undergone radiotherapy to the head and neck, or who have sustained significant burns, may experience this as a long-term consequence of their treatment or injury.
Diagnosis and Assessment
Scarring alopecia cannot be reliably diagnosed on clinical examination alone in most cases. While the clinical picture, history, and dermoscopic findings can strongly suggest the type, definitive diagnosis in primary scarring alopecias generally requires a scalp biopsy. This allows the pathologist to characterise the pattern and depth of inflammation, the degree of fibrosis, and any specific features that distinguish one subtype from another. The distinction matters because management approaches differ significantly between types.
At Regener8 Aesthetics, assessment includes a detailed history of the onset, progression, and distribution of hair loss, examination of the scalp under magnification to assess follicular openings, perifollicular changes, and texture of the affected areas, and a thorough review of medical history and any medications in use. Where the pattern of loss and clinical findings raise the possibility of a scarring process, we do not delay: onward referral to a dermatologist is arranged promptly, and the clinical picture is communicated clearly to support that process.
Dermoscopy provides additional diagnostic information before biopsy. Features such as perifollicular erythema and scaling, absence of follicular openings in affected zones, and the presence of white fibrotic dots can all be assessed dermoscopically and help to distinguish scarring from non-scarring patterns.
Blood tests may be relevant depending on the suspected diagnosis. Where discoid lupus is considered, tests including ANA, anti-dsDNA, and complement levels may be requested to assess for systemic involvement. Regener8 Aesthetics does not perform biopsies or initiate these investigations independently but communicates clearly with the referring clinician to ensure the relevant clinical information is conveyed.
Management Options
The primary management of most scarring alopecias lies firmly within the domain of dermatology and general practice. Immunosuppressive and anti-inflammatory treatments that are the mainstay of managing active lichen planopilaris, frontal fibrosing alopecia, discoid lupus, and other primary scarring alopecias are prescription-only medications that Regener8 Aesthetics does not prescribe. Anyone with suspected or confirmed scarring alopecia must be under the care of a GP or dermatologist for primary management of their condition.
The Role of Dermatology
Dermatologists manage scarring alopecia through a range of interventions depending on the specific diagnosis and degree of disease activity. Options may include topical, intralesional, or systemic corticosteroids; hydroxychloroquine; doxycycline or other antibiotics; topical calcineurin inhibitors; isotretinoin; and, in some cases, immunosuppressants such as mycophenolate mofetil for refractory disease. The goal of all of these approaches is to suppress the inflammatory process and halt further follicle destruction. None of them reverse established scarring.
Optimising Scalp and General Health
For individuals managing scarring alopecia under dermatological care, maintaining good general scalp health, addressing any nutritional deficiencies, and avoiding further physical insult to the scalp are reasonable supportive measures. Avoiding tight hairstyles and heat or chemical processing of the affected area reduces the risk of compounding follicle damage. These are supportive considerations rather than treatments, but worth discussing as part of a holistic picture.
PRP: An Honest Assessment
The evidence base for PRP in primary scarring alopecias is very limited, and it is important to be direct about this. PRP cannot reverse scar tissue or regenerate a destroyed follicle. In a narrow set of circumstances, where an individual is under active dermatological management and there is a specific clinical question about supporting follicles at the active margin of disease, adjunctive PRP might be considered in discussion with the treating dermatologist. It would never be offered as a standalone or primary treatment for scarring alopecia at Regener8 Aesthetics. Honesty about what PRP cannot achieve in this context is non-negotiable.
Psychological Support
Living with an irreversible hair loss condition can be emotionally demanding. Alopecia UK offers peer support, information, and advocacy for people affected by all types of alopecia. The British Association of Dermatologists also maintains patient information resources. We are always prepared to discuss the emotional dimension of scarring alopecia as part of a consultation and can signpost individuals to appropriate support where helpful.

- Scarring alopecia permanently destroys the hair follicle; hair does not regrow in areas where fibrosis has replaced follicle tissue.
- Early diagnosis is essential: the primary objective is to halt progression, and any delay allows further irreversible loss to accumulate.
- Primary types include lichen planopilaris, frontal fibrosing alopecia, discoid lupus erythematosus, CCCA, and folliculitis decalvans, each with distinct features and management requirements.
- Definitive diagnosis requires dermatological assessment and in most cases scalp biopsy; treatment is primarily through prescription medications managed by a GP or dermatologist.
- PRP has very limited evidence in primary scarring alopecias and would only ever be considered as an adjunct under active dermatological management, never as a standalone treatment.
